DEVICE FOR THE HANDLING OF MOLTEN LEAD, TIN, BABBITT, AND OTHER METALS OE MATERIALS.

Application filed March 22, 1922.

To all whom it may concern:

Be it known that I, GILBERT RICHARD COLEMAN, a citizen of the United States, and a resident of Jersey City, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Devices for the Handling of Molten Lead, Tin, Babbitt, and Other Metals or Materials, of which the following is a specification.

My invention relates to certain new and useful devices for the handling of molten lead, tin, Babbitt and other metals or materials. The object of my invention is to provide a safe and quick way of removing molten metal or material from a caldron and at the same time thoroughly stirring and mixing the same during the operation of removal. My invention also provides for distributing the molten metal or material into molds or smaller caldrons as the case may require.

My invention in its preferred form is de scribed and shown hereinafter, but I do not limit my invention to such form as the principle or the invention may be applied, in divers other ways. -Like figures refer to like parts throughout the specification and drawings.

Fig. 1 shows a front View of the construction and combination of the parts of my apparatus. Fig. 2 is a section through 2-2 of Fig. 1. Fig. 3 is a top View of my apparatus.

Referring to the drawing, a cast iron hub 1 is fixed to a shaft 2, which is free to revolve in journals 3 and 3, one journal being bolted to a semi-circular casting i, the other being supported by a channel iron 5 which spans caldron 6 and which is slotted for fastening. Shaft 2 carries a hand wheel 7, for which a slow speed power machine may be substituted if desired. Radially disposed tubular members 8 are secured or bolted into hub 1. Such tubular members may be constructed of standard pipe fittings The number of tubular members to be attached to the hub 1 may be varied according to the circumstances. The tubular members 8 are secured or bolted to holes located as at 9. These holes communicate with intersecting holes whose openings are as at 10. A trough 11 is placed to receive any discharge from the opening of such intersecting holes.

Serial No. 545,681.

The outward portions of the tubular members 8 are bent as shown in the drawings in the direction of the revolution of the hub when the apparatus is operated. The end portion A of said tubular members are made of extra heavy material and are of greater diameter than the main part of the tubular member B. A reducing L C is placed between the parts A and B. To describe this form of end portion of the tubular member I generally use the term bucketed and have so used it throughout my claims. By such term I wish to describe an end portion of greater diameter than the rest of the'tubular member. pose of making this end portion of heavy material and of greater diameter is so that such end portion may possess a greater capacity for gathering up and holding the molten material than the main portion of the tubular members may have for disposing of such material. In this way a large amount of molten material is held in the bu-cketed end portion and is only slowly drawn off as the tubular member revolves.

The molten metal or material retained in the bucketed end portion tends to keep such tubular member at an even temperature throughout the cycle of operation.

My apparatus operates as follows: A molten metal or material is located within the caldron 6. lVhen the shaft 2 is rotated in the direction indicated by the arrow in Fig. 2 the tubes 8 dip into the molten mate rial. contained in the caldron and in their rotation from the position of tube 8 to that of 8 will gather up a quantity 01 said moltenmaterial and will discharge the same from their base later in the cycle at the ap proximate position of 8 or 8 This dis charge will flow into the holes 9 and out of the opening of the intersecting holes at 10 into trough 11. Trough 11 may be a section of angle iron suitably closed at the ends supported on the rib of the caldron by the tour angle iron members 12. The trough 16 carries a discharge pipe 17 over which is fitted a telescopic joint 18. The telescopic joint 18 is a part of the pouring tube 19 and is fastened by link 20 so that it may be swung laterally around the discharge pipe 17. The pouring tube 19 is fitted with the loose joint 21 which allows for an adjustable pouring range for the pouring spout 22.

A strainer or skimmer to remove dross The purlUJ llU

or oxides may be placed in the trough 16. The discharge pipe 17 or pouring spout 22 may readily be fitted with a shutting off cock if desired.

What I claim as new and desire to secure by Letters Patent is:

1. Means for raising molten material consisting of a revoluble hub, having a series of tubular members outwardly afiixed thereto, the end portions of said tubular members being bent forward in the direction of revolution of said hub, said end portions having bucketed orifices adapted to dip into and to gather said molten material as said hub is revolved, a reducing L between the end portion and the main portion of said tubular members, said tubular members being connected at their base with holes located in said hub, which holes communicate with intersecting holes in said hub, a trough connected with said intersecting holes and discharging means connected with said trough.

2. Means for raising molten material consisting of a revoluble hub, having a series of tubular members outwardly affixed thereto, the end portions of said tubular members being bent forward in the direction of revolution of said hub, said end portions having bucketed orifices adapted to dip into and to gather the molted material as said hub is revolved, said tubular members being connected at their base with holes located. in said hub, which holes communicate with in tersecting holes in said hub, a trough connected with said intersecting holes, a discharge pipe fitted with a telescopic joint connected with said trough and an adjustable pouring tube connected with said discharge pipe.

3. The combination of a revoluble hub, a series of tubular members outwardly affixed thereto the end portions of said tubular members being bent forward in the direction of revolution of said hub, a reducing L between the end portion and the main portion of said tubular members, said tubes having bucketed orifices and connected at their base with holes located in said hub and discharging means connected with said holes.

4. The combination of a revoluble hub, a series of tubular members outwardly afiixed thereto, the end portions of said tubular members being bent forward in the direction of revolution of said hub, a reducing L between the end portion and the main portion of said tubular members, said tubes having bucketed orifices and connected at their base with holes located in said hub which holes communicate with intersecting holes adapted to discharge into a trough and adjustable discharging means connected with said trough.

5. The combination of a series of radially disposed tubular members adapted to revolve in a given direction, the outward portions of said tubular members being bent forward in said direction, said tubular members having bucketed orifices and a reducing L between the bucketed orifice and the main portion of said tubular members, and discharging means connected with the base of said tubular members.

"6. A means for raising molten material consisting of a series of radially disposed tubular members adapted to revolve in a given direction, the outward portions of said tubular members being bent forward in said direction, said tubular members having bucketed orifices, adapted to dip into and to gather the molten materialwhen said tubular members are revolved and having a reducing L between the bucketed orifice and the main'portion of said tubular members, and of discharging means for the molten material connected with the base of said tubular members. a

In testimony whereof, I havesigned my name to this specification.

GILBERT RICHARD COLEMAN.
